The chisina kutsetseka tichimhanya: inobudisa Solid Mechanics

Chisina kutsetseka tichimhanya chinhu chinokosha, mitemo inokosha zvakasikwa. Hwakabatana zvakananga chete symmetry ehupfumi ari nzvimbo munyika mumuviri yatiri zvose kurarama. Nokuda mutemo kuchengetedza ayo, tichimhanya rinorondedzera zvavaisiita kwatiri mitemo inofamba zvinhu mitumbi iri muchadenga chaiko. ukoshi unomiririra uwandu translational kana rotational inofamba.

The chisina kutsetseka tichimhanya, anonziwo "kinetic", "angled" uye "orbital", chinhu chinokosha hunhu, izvo kunoenderana mashoko kurema muviri, ayo kuparadzirwa unhu panyaya yokufungidzira bhuku akabatana uye kubvongodzwa nokukurumidza. Zvinofanira yakajekeswa kuti hurongwa ose kutenderera ane zvimwewo dudziro. Kunyange Linear inofamba nenzira imwe zvemasanga pfungwa iri nzvimbo zvinogona kunzi sezvo rotational, akamubata zvekufungidzira akabatana.

Chisina kutsetseka tichimhanya uye mitemo kuchengetedza ayo akagadzira, Rene Descartes aishanda translationally zvinofamba mugadziriro zvokunyama pfungwa. Zvisinei, kuti tirambe kuti muhombe inofamba mhando haana kutaura. Papera chete zana Leonardom Eylerom, uye ipapo mumwe Swiss musayendisiti, yefizikisi uye nyanzvi yemasvomhu Daniel Bernoulli kufundwa hurongwa majana pamusoro wakaiswa nechepakati akabatana, zvakanzi vakagumisa kuti uyu mhando kufamba muchadenga mabasa kupiwa mutemo.

Kumwe kuferefeta kunge zvakazara kwakaratidza kuti pasina nechitarisiko simba Verenga chigadzirwa uremu pfungwa dzose dziri hombe hurongwa nokukurumidza uye daro kuti musimboti kutenderera anoramba kuzochinja. Zvishoma Papera, musayendisiti French Patrikom Darsi mazwi aya vakanga vakanyorwa maererano yacho kupararira achishandisa nharaunda vectors kuti zvokutanga inoramba kuti iyoyo nguva. Izvi akabvumira kuti kurondedzera chisina kutsetseka tichimhanya ane zvinhu pfungwa nevamwe anozivikanwa yokudenga hurongwa postulates uye, kunyanya, kuti rinokosha nzvimbo mapuraneti inofamba Ioganna Keplera.

Nguva tichimhanya ane vanachandagwinyira muviri - wechitatu simba shanduka kuti izvo zvinoshanda zvokudya chinokosha mutemo kuchengetedza. Anoti kuti pasinei hunhu uye mhando inofamba pasina nechitarisiko pesvedzero ukoshi iri kwayo yoga zvinhu Hurongwa achagara kuramba kuchinja. Izvi rokuti rwomuviri chaidzo vamwe kuchinja chete kana vasiri razero panguva was mauto.

Kubva mutemo uyu rinoratidzawo kuti kana M = 0, shanduko chero kure pakati muviri (zvinhu pfungwa maitiro) uye nechepakati kutenderera akabatana hazvo kukonzera kuwedzera kana kudzikisa ayo mwero yadzo dzichitenderera pakati. Somuenzaniso, munhu anorovedza muviri achiita chakapidiguka mudenga kuti mashoma majana, pakutanga achifinyamisa muviri wake bhora. A Ballerina kana mufananidzo muaizi rotates mu pirouette, akatunhidzwa maoko mumaoko, kana vachida sipidhi, ndiEzekieri, achizviendesa navo muviri, kana kuedza chamupidigori panguva yepamusoro nokukurumidza. Saka, muna mutambo nounyanzvi kushandisa mitemo inokosha zvakasikwa.
